Insulation News: Rockwool CEO Comments on 2012 Annual Report
CEO COMMENT: TOWARDS A TRULY GLOBAL BUSINESS
CEO Eelco van Heel presents the current status and future
directions for the ROCKWOOL Group as presented in the Annual Report 2012:
Eelco van Heel, CEO of the ROCKWOOL Group
"We have a solid platform and a strong position to build our future growth
In 2012 the Group put full force behind the execution of its
Rock the Globe strategy – developed and fine-tuned based upon the assumption
that the world economy in general, and the building industry specifically, will
remain very challenging in the years to come.
Our core European insulation business will remain the
backbone of our success where we are optimising activities on all fronts. This
includes more sophisticated and customer oriented routes to market for our
products and systems and a major re-engineering of our production set up. We
are also focusing keenly on raising market awareness of the unique combination
of properties naturally intrinsic to our ROCKWOOL stone wool products. These
initiatives are supported by increased efforts in the public affairs area to
inform politicians and legislators about the advantages for society of better
fire, acoustic and total energy performance of buildings.
We continue to invest heavily in accelerated growth and
improved profitability of our non-insulation Systems activities, where
innovative new products and systems play an important role.
In order to reduce further the effect of our high exposure
to developments in the European market, the Group’s penetration in other
geographical areas continues. During 2012, our fourth insulation factory in
Russia was commissioned successfully, and decisions were announced to
substantially increase capacity in North America as well as Northern China.
The year 2013 will not be an easy one – to say the least.
The ROCKWOOL Group is geared managerially, as well as financially, to tackle
the challenges head on, and the Group is fully prepared to pick the fruits on
the top as well as on the bottom line, as soon as the global economy turns into
a positive mode.

Next up in the series we are doing on pipe insulation is "flexible foams"; a category that includes polyethylene and expanded nitrile rubber.
Polyethylene Pipe Insulation Climaflex pipe insulation is the UK's leading brand for polyethylene pipe insulation. This is the grey foam that most people are familiar with, the kind you would traditionally find in garden centres for example. Polyethylene is the cheapest, widely available product in the market. People very often wrongly assume cheap means poor quality, this is not the case with a brand such as Climaflex. It has a thermal conductivity of 0.034 W/m.K at 0°C which is broadly equal to that of any other flexible foam, and it also has a much higher "μ factor" than other foams, making it more resistant to moisture ingress. These facotrs make it ideal for use around the home, being easy to work with and providing good insulation. The material can be purchased in 1m and 2m lengths, and is available in wall thicknesse…
Our Beginners Guide series of blogs will look at the common areas of pipe insulation lagging that you will want to look at when choosing your product. This guide will be of most interest to the DIY installers, but some of our later guides will cover more complex products and areas of application.
One of the things we get asked about a lot is what the dimensions quoted for pipe insulation actually mean. You will always see three measurements quoted when describing pipe insulation; Wall Thickness, Bore Size and Length.
In the below diagram, A is the "Bore" and B is the "Wall".
Wall thickness is very simply how much insulation you have; so for example if you have 13mm Wall pipe insulation, then that means you have 13mm of insulation on either side of your pipe. This thickness is very often one of the most important part of your decision; too thin and you might not get the results you are looking for but too thick and it might not fit between your pipe and the wall.
With the cold weather approaching we thought it would be a good idea to touch on how best to protect your pipes from frost this winter.
When dealing with frost protection on pipes inside a building your aim with insulating them is to delay the onset of freezing for as long as possible; it is not possible to guarantee a pipe will not freeze by insulation alone. The better the insulation, and the thicker the insulation, the longer you will give yourself. Under normal circumstances you aim to give yourself about 8-10 hours protection against sub zero temperatures. With pipes inside a home this is usually long enough to be sure the pipes will not freeze.
Ice formation inside the pipes will lead to an increase in pressure. As the water tries to flow this pressure will increase, and eventually will lead to the pipes bursting. A burst pipe can cause a lot of problems, not least of which is a lot of damage to your property and a lot of expense incurred.
